Product Description P/N: EHB34030
Description
The Square D EHB34030 is a standard-interrupting molded case circuit breaker designed to provide dependable overcurrent and short-circuit protection for commercial electrical panelboards. This 30-amp, three-pole device utilizes thermal-magnetic trip technology to monitor electrical loads and automatically disconnect power during hazardous fault conditions. By actively securing branch circuits, the breaker prevents permanent damage to downstream industrial equipment and ensures continuous facility operation.

Information About EHB34030
The EHB34030 is a compact E-frame circuit breaker engineered specifically for bolt-on installation within compatible Square D NEHB electrical lighting and distribution panels. It features a rugged thermoset composite housing that safely contains internal arc flashes and provides excellent dielectric strength within crowded mechanical rooms. Electrical contractors install this 480Y/277 VAC rated component to safely isolate and manage three-phase alternating current power across critical facility infrastructure. The unit relies on proven bimetallic and electromagnetic sensors to detect both sustained thermal overloads and instantaneous short circuits with high accuracy.
Key Features:
● Thermal-Magnetic Trip Unit: Combines temperature-sensitive bimetal elements and electromagnetic sensors to detect varying fault profiles accurately.
● Bolt-On Mounting: Facilitates a secure, vibration-resistant physical connection directly to the busbars of compatible NEHB panelboards.
● E-Frame Construction: Utilizes a compact, high-strength molded case housing to conserve valuable space within commercial switchboards.
● Three-Pole Configuration: Engineered to safely distribute and protect three-phase alternating current power within industrial networks.
● Standard Interrupting Rating: Delivers a 14 kA interrupting capacity at 480 VAC to reliably clear electrical faults and prevent circuit damage.
● Phase Isolation Barriers: Incorporates internal arc chutes to suppress electrical arcing and prevent dangerous phase-to-phase flashovers during a trip.
The EHB34030 delivers the reliability and precision required for secure power distribution and effective fault prevention in modern lighting and distribution panels.
